Why This WOT Rebuild Kit Makes Sense for Your AR
Look, I’ve handled my share of worn-out triggers, both on the range and in the field up here in North Dakota. The appeal of a full upgrade kit like this isn’t just about fixing something that’s broken—it’s about preventative maintenance and getting ahead of wear. For the price of a couple boxes of premium ammo, you can essentially renew the heart of your fire control group. This is the kind of practical upgrade that fits the concealed carry lifestyle: reliable, affordable, and it keeps your gear running right without a huge investment. It’s for the shooter who values performance but also keeps an eye on the bottom line.

The Straight Talk: Pros & Cons
Based on handling this kit and talking to folks who’ve installed it, here’s the honest breakdown.
What You’ll Like:
- ✅ Cost-Effective Revival: Breathes new life into your existing WOT trigger for a fraction of a full replacement cost.
- ✅ Complete Package: Has all the high-wear items you need in one box—no guessing or making multiple orders.
- ✅ Improved Material Spec: The tool steel and heat-treating on key components aim to offer better longevity than some original factory parts.
- ✅ Maintains Familiarity: You keep the trigger you’re used to, just with a refreshed, smoother feel.
- ✅ Smart Maintenance: Perfect for round-count-based preventative maintenance or bringing a used gun back to spec.
What to Consider:
- ❌ Not a Drop-In Trigger: This is a rebuild kit. You need some technical know-how, punches, and a vise block to install it correctly. If that sounds daunting, a complete drop-in trigger unit might be a better fit.
- ❌ For WOT Systems Only: This isn’t a universal AR trigger kit. It’s designed specifically for WOT triggers. If you have a different system, check our FRT Triggers category for other options.
- ❌ Restores, Doesn’t Redesign: It brings your WOT back to its intended function, but it won’t change its fundamental pull weight or reset characteristics beyond the original design.
Who Should (and Shouldn’t) Buy This Kit
Buy it if:
- You own a WOT trigger that’s seen high round counts and is starting to feel worn.
- You bought a used firearm with a WOT already installed and want to ensure reliability.
- You’re proactive about maintenance and want a kit on hand for the future.
- You’re comfortable with basic gunsmithing tasks on your AR-15 lower receiver.
- You want to maximize the value and lifespan of your existing gear.
Skip it if:
- You’re looking for a completely new trigger feel or a lighter pull weight (browse our AR Triggers instead).
- You don’t own a WOT trigger system—this kit is model-specific.
- You have zero interest in disassembling your fire control group. In that case, a complete, pre-assembled unit is the way to go.
- Your WOT trigger is damaged (e.g., a sheared hammer) beyond simple wear parts. You may need individual replacement components.
Common Concerns & Questions
“Is this going to be a huge project to install?”
Not huge, but it requires focus. If you’ve ever swapped a mil-spec trigger for an aftermarket one, you have the skills. You’ll need a solid workspace, a set of roll pin punches, and maybe a hammer. Take your time, follow a guide (see YouTube button below), and keep parts organized.
“Will this fix trigger slap or a gritty feel?”
In most cases, yes. Those issues are often caused by wear on the engagement surfaces of the hammer and sear, or by worn springs—all of which are replaced in this kit. A proper installation should restore a clean break and reset.
“My WOT works but feels slow. Will this help?”
Potentially. A sluggish reset is frequently due to a tired disconnector or weak springs. Replacing those components can snap that reset back to its original speed.
Frequently Asked Questions
What exactly is included in the WOT Complete Upgrade Kit?
The kit typically includes all the high-wear, consumable parts for a WOT trigger system. This means replacement hammer, sear, disconnector, trigger, and all related springs and pins. It’s designed to give you every part that might need refreshing after extensive use.
Do I need any special tools to install this rebuild kit?
You’ll need standard AR-15 armorer’s tools: a set of roll pin punches, a gunsmithing hammer, a vise block to secure your lower receiver, and possibly some pin starter tools. A well-lit, organized workspace is key.
Will installing these parts affect the legality of my trigger?
This kit contains replacement parts intended to restore the original function of your legally owned WOT trigger. It does not alter the firing cycle or design intent. As always, you are responsible for understanding and complying with all federal, state, and local laws regarding your firearms.
How do I know if my WOT trigger needs this kit?
Signs include a mushy or inconsistent break, a slow or weak reset, failure to reset entirely, visible wear on the hammer or sear engagement surfaces, or simply a high round count (think several thousand rounds). If performance has degraded, this kit is the fix.
Is there a warranty on these parts?
Manufacturer warranties vary. These are replacement components built to a high standard. For peace of mind, Imbertsmithersarms offers a 30-day return policy on all unused items if you encounter any issues.
